OCR & Text Extraction

Extract usable text from images, screenshots, scanned pages and PDFs with OCR and text tools for copying, searching, editing and reuse.

Know when OCR is needed

Text extraction works differently on real document text, screenshots and scanned pages.

A normal digital PDF may already contain selectable text, so direct extraction can be faster and more accurate than OCR. OCR is useful when the words exist only as pixels—for example in a scan, photograph or screenshot. The recognition engine estimates characters from the image, which means the result should be treated as editable text that may need checking rather than a guaranteed transcription.

What improves recognition quality

Sharp, upright text with good contrast is easier to recognize than blurred, skewed or low-resolution material. Small fonts, handwriting, decorative typefaces, complex tables and text over patterned backgrounds can reduce accuracy. If a page is sideways, rotate it before recognition. For screenshots, crop away unrelated interface elements when they interfere with the text area.

Review important extracted text

Names, account numbers, dates, decimal points and similar short strings can be especially costly when one character is wrong. Compare important fields with the source before using extracted text in a form, spreadsheet, contract or data workflow. OCR is excellent for making content searchable and reusable, but high-stakes information still benefits from human verification. If the source contains several languages, unusual symbols or dense tables, compare more of the extracted text before treating it as complete.
